Description
Product Introduction
The GE IS200GFOIH1A is a Mark VIe series general purpose fiber optic I/O module that provides optical signal input and output capability for Mark VIe control systems. This I/O pack enables fiber optic I/O functionality for applications requiring noise-immune, long-distance optical communication.
The H1A revision provides fiber optic I/O capability with specific hardware configuration. In our field experience, the GFOI provides essential fiber optic I/O for noise-sensitive installations. For facilities requiring fiber optic I/O capability, the GFOI provides the necessary solution.

Frequently Asked Questions (FAQ)
Can I hot-swap this IS200GFOIH1A into a running Mark VIe system?
We strongly advise against it. The GFOIH1A has shown unpredictable behavior when inserted into a powered backplane. Schedule a controlled outage, de-energize the rack, and swap it during planned maintenance.
What is the difference between the GFOI and FOSA modules?
The GFOI is a general purpose fiber optic I/O module providing both input and output capability. The FOSA is a fiber optic adapter module providing conversion between electrical and fiber signals.
How do I verify this is a genuine GE module?
We source exclusively from GE-authorized liquidations. Our verification includes OEM packaging inspection, serial number cross-check against GE records, and PCB inspection for GE-specific markings.
What is the expected lifespan of this unit?
We see MTBF around 145,000 hours for the GFOIH1A. We have seen these units exceed 15 years in field service.
